Easy to use and mount monitors on it.  The problem is, I mounted 3 exact same model 27" Displays on this triple mount and the outside display would not adjust enough to line up horizontally with the center Display, even with the center monitor at it lowest possible location  The two outside monitors were 1/2 inch lower than the center one.  This device is rated to hold up to 22lb displays.  Mine were 8 pounds.  This device just needs to be re engineered for more adjustments up and down
